Description of problem: A good deal of the plugins crash on Fedora 28, it is probably due to new hardening flags introduced in F28. Plugins that crash: compressor, deesser, gate, monosynth ... Some crash upon opening the settings of the plugin, for example multibandgate. Others work as expected (filter, reverb, crusher, vocoder) Version-Release number of selected component (if applicable): 0.90.0 How reproducible: Always. Steps to Reproduce: 1. calfjackhost monosynth Actual results: /usr/include/c++/8/bits/stl_vector.h:932: std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::operator[](std::vector<_Tp, _Alloc>::size_type) [with _Tp = calf_plugins::jack_host::port; _Alloc = std::allocator<calf_plugins::jack_host::port>; std::vector<_Tp, _Alloc>::reference = calf_plugins::jack_host::port&; std::vector<_Tp, _Alloc>::size_type = long unsigned int]: Assertion '__builtin_expect(__n < this->size(), true)' failed.
